Alright, I'm hoping someone can help me here. I'm having some major problems with my MX518. Plain and simple the scroll wheel has a mind of its own. It constantly scrolls up and down, (mostly down, up sometimes) for no reason at all. Is there anyway I can disable the mouse wheel within Windows or some other software that I can use? Writing this here is a major pain, forget about gaming.... my weapons constantly switch on there own because of the scroll wheel. Any help is much appreciated. EDIT: I forgot to say i thought maybe it was a USB port problem, but i tried another port. didn't help.
